System Analysis and Design Quiz

Analysis Phase

• The main focus of the Analysis phase in software engineering is on understanding the problem domain and identifying the requirements of the system.

UML Diagrams

• The dynamic behavior of a system in UML is primarily represented using sequence diagrams or state machine diagrams.
• Deployment diagrams are used to represent the physical deployment and configuration of system components.

Process and Use Cases

• The primary purpose of a flow of events in a process or use case is to describe the sequence of activities and interactions between actors and the system.

SDLC Phases

• The activities 'Requirements Elicitation' and 'System Design' take place in the Analysis and Design phases of the Software Development Life Cycle (SDLC), respectively.

Modeling

• A static model focuses on representing the structure and organization of the system's objects and their relationships.

System Design

• The main purpose of subsystem decomposition is to allocate system functionality and responsibilities to subsystems and components.
• Robustness in system design refers to the ability of a system to continue functioning correctly even when errors or exceptions occur.
• In the context of design trade-offs, a common trade-off is between functionality and performance.
• Identifying design goals helps to define the desired properties and characteristics of the system.

Design Process

• One potential difficulty mentioned in the text about the design process is resolving conflicting design goals and trade-offs.

UML Notation

• UML notation commonly used to represent subsystems is packages.

Concurrency Control

• The main purpose of concurrency control in system design is to manage access to shared resources and ensure consistency and integrity.

Design Guidelines

• Availability in the context of system design refers to the ability of a system to be accessed and used when needed.
• When distributing classes on subsystems, the designer should follow the guideline of grouping related classes together to minimize dependencies and improve cohesion.
